PSO shouldn't whine about it in the customer's presence. That is unprofessional. The beef is with Motiv, not the customer as he/she did not cause or ask for this issue to occur.
Also, it is not necessarily more foot traffic, and in the long run, as Big mentioned, could cost the PSO a potential sale. Instead of purchasing a new ball, PSO gets the replacement ball and is out the door.
So this is not a great big way of producing unexpected traffic for the PSO.
